Different classifications based on outside diameter are not interchangeable, but can often be connected with specialty adapter Pipe Sizing Classifications Based on Outside Diameter Iron Pipe Size (IPS) - PVC & cpvc Pressure Pipe and drainage waste & Vent DWV pipe, forms one of the most widely used sizing classifications including Schedule 40, 80 & 120 pipe and Class pipe in various Standard Dimension Ratios (SDR).

5 Threaded pipe requires a 50% reduction in the Pressure Ratings stated for plain-end pipe @ 73 F. Threading recommended for Schedule 80 or heavier walls only. Maximum service temperature for PVC is 140 F. Maximum service temperature for cpvc is 200 F. The Pressure rating of the pipe must be de-rated when working at elevated resistance data should be referenced for proper material selection and possible de-rating when working with fl uids other than Pipe Size (in) WallNominal PSI*1 Pipe Size (in) WallNominal PSI*1 Pipe Size (in) WallNominal .. - Class 315 Maximum Working Pressure 315 psi (all sizes)Nom.

The specifi ed derating factors for PVC or for cpvc are suit-able for pipe conveying water at elevated temperatures. To determine elevated temperature rating, multiply 73 F [23 C] Pressure rating by appropriate factor shown in the working near maximum specifi ed temperature, solvent cement joints are recommended in place of threaded connec-tions.

7 Where disassembly is required at elevated temperatures use Spears Special reinforced (SR) adapters, fl anges, unions or grooved coupling Schedule 80 or heavier wall thickness pipe (PVC or cpvc ) should be threaded. Do NOT thread Schedule 40 pipe or other thinner-walled pipe such as SDR , SDR 21, SDR 26, etc. Threading requires a 50% reduction in the pipe s specifi ed Pressure rating @ 73 Chemical Resistance Data for Pressure Piping informa-tion for both chemical compatibility and potential temperature limitations when using certain Temp ( F)De-Rating : 2" PVC SCHEDULE 80 @ 120 F = 400 psi x = 160 psi max.
